In the Oracle database, the role of the password (password) is self-evident. It is used to verify user identity and protect data. The first line of defense for security. This article will take the role and importance of Oracle passwords as the theme, combined with specific code examples, to explore how to effectively manage and protect Oracle passwords to ensure database security.

Password is a way of user authentication. Only through verification can you access database resources. By setting complex and secure passwords, you can effectively prevent unauthorized users from accessing the database and ensure the confidentiality and integrity of the data. In addition, passwords are also the basis for database security management. Good password management can prevent the database from being maliciously invaded or data leaked.
